Abstract—The thermolysis of shale (regular shale from the Kenderlyk field in Kazakhstan) with the recirculation of high-boiling shale-oil fractions (above 340°C) in a system with a solid heat source is investigated by balance analysis. Such recirculation boosts the quality of the shale oil obtained. It is characterized by lower density, lower sulfur content, and higher yield of the light fractions employed in automobile fuels (gasoline and diesel fuel).
